cost of 1 book = $2.45
Now finding cost of 10 books:
cost of 10 books = $2.45 *10
cost of 10 books = $24.5

Answer:
Do you have an image because I'm a bit confused with you just asking the measure of PSQ.
Step-by-step explanation:
Answer:
x = [-b +-sq root (b^2 -4ac)] / 2a a=2 b=-2 c=3
x = [--2 +- sq root(4 - 4*2*3)] / 2*2
x = [2 +- sq root (-20)] / 4] / 4
x1 = 2 + 4.472135955 i / 4
x1 = .5 + 1.1180339887i
x2 = 2 - 4.472135955 i / 4
x2 = .5 - 1.1180339887i

Answer:
1/2 ; 1/4
Step-by-step explanation:
Number of cards in a deck = 52
Number of red cards = 26
Number of spades = 13
Probability of event A :
P(A) = required outcome / Total possible outcomes
P( red card) = number of red cards / total cards in deck
P(red card) = 26 / 52 = 1/2
P(spade) = number of spades / total cards in deck
P(red card) = 13 / 52 = 1 / 4
